Brian Mann works as an artist and graphic designer, and lives in Los Angeles. He has been invited to Städelschule in the framework of John Knight's exhibition at Portikus, which they developed in close collaboration. John Knight and Brian Mann have been working together on publications since a number of years. Brian will give a lecture based on a talk given at the most recent Marxist Reading Group conference at the University of Florida. The presentation wanders around the role of decision-making and choosing in popular culture and art today.
